In 1950, Jan Hendrick Oort proposed the existence of a cloud 10,000 - 100,000 AU from the sun. (Named the Oort cloud) that surrounds our solar system. The cloud contains trillions of loose lumps of dust and volatile gases, near-perfect examples of the stuff planets were made of.

Now. My question is, if this cloud surrounds our solar system. Does it not hinder our view of what lies beyond?
